Two men have been taken to hospital with serious injuries after a gas explosion at an industrial estate in Nottingham.
Emergency services were called to Colwick Industrial Estate shortly after 10:00 BST.
The fire service said there had been a gas explosion and a “tanker had collapsed”, but there was no blaze by the time crews arrived.
Police said they “don’t believe the incident is terrorism-related”.
Bob Winter, medical director for East Midlands Ambulance Service, said paramedics specially trained to deal with major incidents were dispatched.
“We treated two patients on scene,” he said.
“Both had suffered serious injury and were taken to the Queen’s Medical Centre in Nottingham by ambulance.”
